WOVEN-WI RE SEAT.

SPECIFICATION forming part of Letters Patent No. 250,843, dated December13, 1881.

' Application flied March 14,1881. (No model.)

To all whom it may concern:

Be it know-n that I, HENRY ROBERTS, of

Hartford, '1n the county of Hartford and State,

of Connecticut, have invented certain new and useful Improvements inWoven-Wire Seats; and I do hereby declare that the following is a full,clear, and exact description thereof, whereby a person skilled in theart can make and use the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My invention relates to car seats, sofas, lounges, &c., in which anelastic coiled wire fabric is stretched upon a frame to form a seat or abasis for the upholstering.

The object of my invention is to avoid and obviate the difficultieswhich have heretofore been encountered in the use of this material forthe purpose named, which have been chiefly a sagging or want ofsustaining-power in the middle'part of the seat when the fabric wassuspended from end to end of the frame.

In the accompanying drawings, illustrating my invention, Figure l showsa front view of a seat of my improved construction, not upholstered, inorder to show the construction. Fig. 2 is an end view of the same. Fig.3 is a cross-section through the middle of the seat.

In Fig. 1 one of the front corners is cut away so as to show theinterior parts.

A is the elastic wire fabric forming the seat, and B is a fabric of thesame kind forming the back of the seat. The supporting-frame of the seatA is constructed with two side bars, C O, and two end bars, D D,recessed into the ends of the side bars and extending slightly abovethem. The end bars are curved upward so as to give a crowning form tothe seat, and are constructed of two parts, D and D', between which theflattened edge of the fabricis clipped and secured by the screws E. Theelastic fabric thus attached to the end bars is stretched so as to giveit a suitable tension, and the end bars are secured to the side bars bythe screws F, to hold the whole rmly in place.

G G Gr are thin exible springs, one or more of which may be used, havinga top surface of the form and curve of the Linder side of the wirefabric, and bending down so as to lie depression ot' the fabric.

against and be attached to the side bars, G, by means of screws or boltsG. These springs are intended to yield downward on the top and spreadoutward at the sides to conform to any They form partial and yieldingintermediate supports, which prevent the sagging, like ahammock, of theelastic fabric as it ordinarily does to some extent when supported onlyat the ends, and. removes the great objection to its use for seatsresult ing from this cause.

This seat can be used constructed as above described, or it may becovered or upholstered in the usual manner, applying the covering or-upholstering directly upon the top of the elastic fabric, which formsan elastic spring-surface of great strength and durability.

The frame for the back of the seat has end bars of the same constructionabove described, from which the elastic fabric is suspended from end toend; but the side bars are differently arranged, so as to avoid having ahard ridge upon the top of the back. They are placed sufficiently infrom the side of the fabric to admit of the upholstering being carriedaround the top edge without coming directly upon the hard edge of theside bar, and if used Without upholstering the top edge of the fabricpresents a yielding surface. This construction is shown in Fig. 3, whereH H are the side bars. They are attached to the end bars, J, by thebolts K. The side bars thus coming farther under the curve of the fabriccan be made somewhat higher or nearer the fabric, which gives a strongerconstruction.

What I claim as my invention is- The combination of the yieldingtlatspring Gr, extending from side bar to side bar, with the elasticcoiled-wire fabric A, suspended from the curved end bars, J, and theside bars, C, substantially as described.

2. The combination of the curved end bars, J, the elastic coiled-wirefabric B, and the side bars, H, placed entirely within the edges andunder the curved surface of the fabric B, substantially as described.

HENRY ROBERTS.
